what is the DEFAULT_MAX_SESSION_DURATION. Im referring to the following plugin, https://github.com/livekit/agents/pull/2360. can you explain how to use this and what value i should set

Thanks for reaching out, Ahmed. I'm an AI assistant and I'm here to help. Give me a moment while I research this topic.

lets say my conversation runs for 30 minutes, what will happen if i dont declare max_session_duration? or is it required for me to decalre max_session_duration

Just a heads-up: if you don’t set

max_session_duration

, it’ll default to 20 minutes (1200 seconds). When a conversation goes over this time, the connection will reset. This means the current session closes and a new one starts to keep things running smoothly and manage resources well. Don’t worry—the reset process is designed to be as smooth as possible. LiveKit will try to reconnect automatically, which might involve re-establishing the signaling WebSocket and restarting the WebRTC connection. You might notice a short pause in audio or video while this happens. Setting

max_session_duration

isn’t required, but if your chats usually last longer than 20 minutes, you might want to increase it to avoid those extra reconnections. If you’d like, I’m here to help you set it up!

also, lets say that i encounter any error such as a timeout or something else, will this plugin automatically trigger a restart?

Hey there! Just to make sure I’m on the right track—are you asking about automatic restarts for a specific plugin like OpenAI RealtimeModel, or are you referring to LiveKit’s core features? Let me know so I can give you the best possible answer!

Hey there! Just wanted to share how LiveKit keeps things running smoothly by focusing on staying connected. If the network hiccups or connection drops, it will try to reconnect automatically—sometimes by doing an ICE restart or a full reconnection. However, it doesn’t automatically restart sessions for errors like timeouts. Now, about plugins: • AWS Plugin: It’s pretty smart and will restart sessions automatically if it hits certain validation errors, like stream closures. • Google Plugin: If it runs into a timeout (like a DeadlineExceeded error), it’ll restart the session for you. • OpenAI Plugin: When timeouts happen, it resets the session and triggers a reconnect event to keep things going. If you’re using a particular plugin, it might have extra ways to handle errors and restart sessions on its own. Feel free to ask if you want me to dive into details about any plugin or situation—you’re not alone in this!

which version does this feature work on. •

patch

-

livekit-plugins-openai

Just a heads-up! The features for automatic restarts and

DEFAULT_MAX_SESSION_DURATION

are available in these versions: • livekit-agents: Available from version 0.11.0 onwards • livekit-plugins-openai: Available from version 0.10.5 onwards For the smoothest and most up-to-date experience, I’d recommend using the 1.0.x versions (like

livekit-agents==1.0.11

and

livekit-plugins-openai==1.0.11

). If you’d like a hand setting these up or have any questions, just give me a shout—I’m here to help! Sources: livekit-plugins/livekit-plugins-openai/livekit/plugins/openai/stt.py | agent/requirements.txt | requirements.txt

and just to be clear, i have not declared max_session_duration, will it still work?

Yes, no worries if you haven’t set `max_session_duration`—it’ll still work just fine. The system will simply use the default session duration of 20 minutes (1200 seconds). So after 20 minutes, the session will automatically reset and reconnect, just like usual. But if you need your session to last longer or shorter, you can easily set the

max_session_duration

parameter to fit your needs. Just let me know if you want a hand with how to set it up—I’m happy to help!
